Test Procedure (continued)
Hydraulic System: Testing the Hydraulic System
E. Release the traction pedal, open the flow control valve fully, move the
throttle to low speed, and shut off the engine.
17. If the relief pressure can not be met or is greater than specified, the traction
relief valve is damaged and should be replaced.
18. The under load test flow reading (step 15C) should not drop more than 12%
when compared to the no load test flow reading (step 14B). A difference
of more than 12% may indicate the hydraulic pump is worn and should be
repaired or replaced.
19. After you complete the testing, disconnect the tester and connect the hose to
the pump fitting.
20. Rotate and lock the radiator in correct position.
21. Rotate the fuel tank into position and secure it with the bolt.
22. Start the engine, check for hydraulic leaks, and make repairs as required.
Properly service the system quantity before returning the machine to service.
